How we approach skylight blinds & solar control in Porthmadog
Thinking about skylight blinds & solar control in Porthmadog? The short answer: electric blinds, blackout and solar-control upgrades for rooflights. The longer answer depends on your roof, which is why we survey before we price.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Think of skylight blinds & solar control for bedrooms, nurseries and south-facing kitchens.
Porthmadog is around 33 km from Bangor, Gwynedd, and we survey and fit throughout that part of Gwynedd, including the LL49 district.

Things we check at survey

Planning, building control and Porthmadog
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Skylight blinds & solar control in Porthmadog: questions
Will a blind stop a rooflight getting hot?
An internal blind helps with glare but some heat still gets in behind it. Solar-control glass or an external shade does more for heat.
Are electric blinds worth it?
For high rooflights you cannot reach, yes. Solar-powered models avoid new wiring.
Can you fit a blind to my existing rooflight?
Usually, yes — if there is enough depth in the reveal for the cassette and rails. We measure first.
Will I need planning permission in Porthmadog?
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed.
Do I need to be at home for the survey in Porthmadog?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
